Nginx服務啓動、中止和重啓等操做的SHELL腳本

因爲使用源碼編譯安裝Nginx,不會像yum install那樣自動生成Nginx服務控制腳本,因此須要本身添加一個操做腳本。谷歌上搜了一下,shell腳本的代碼基本相似,所以本身稍微整理改動了下。html

下面的shell腳本內容,須要根據Nginx實際編譯安裝的配置,修改NGINX_CONF_FILE="/etc/nginx/nginx.conf"lockfile=/var/lock/nginx.lock這兩個參數(即前文《2015博客升級記(三):CentOS 7.1編譯安裝Nginx1.9.0》中的configure配置nginx

#! /bin/bash
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15
# description:  Nginx is an HTTP(S) server, HTTP(S) reverse \
#               proxy and IMAP/POP3 proxy server
#
# processname: nginx
# config:      /etc/nginx/nginx.conf
# pidfile:     /var/run/nginx/nginx.pid

# Source function library.

# Source networking configuration.

# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0

nginx="/usr/sbin/nginx"
prog=$(basename $nginx)

NGINX_CONF_FILE="/etc/nginx/nginx.conf"

[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx

lockfile=/var/lock/nginx.lock

start() {
    [ -x $nginx ] || exit 5
    [ -f $NGINX_CONF_FILE ] || exit 6
    echo -n $"Starting $prog: "
    daemon $nginx -c $NGINX_CONF_FILE
    retval=$?
    echo
    [ $retval -eq 0 ] && touch $lockfile
    return $retval
}

stop() {
    echo -n $"Stopping $prog: "
    killproc $prog -QUIT
    retval=$?
    echo
    [ $retval -eq 0 ] && rm -f $lockfile
    return $retval
}

restart() {
    configtest || return $?
    stop
    sleep 1
    start
}

reload() {
    configtest || return $?
    echo -n $"Reloading $prog: "
    killproc $nginx -HUP
    RETVAL=$?
    echo
}

force_reload() {
    restart
}

configtest() {
  $nginx -t -c $NGINX_CONF_FILE
}

rh_status() {
    status $prog
}

rh_status_q() {
    rh_status >/dev/null 2>&1
}

case "$1" in
    start)
        rh_status_q && exit 0
        $1
        ;;
    stop)
        rh_status_q || exit 0
        $1
        ;;
    restart|configtest)
        $1
        ;;
    reload)
        rh_status_q || exit 7
        $1
        ;;
    force-reload)
        force_reload
        ;;
    status)
        rh_status
        ;;
    condrestart|try-restart)
        rh_status_q || exit 0
            ;;
    *)
        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
        exit 2
esac

將上面的shell腳本內容以Unix格式(不能用dos哦)保存並命名爲nginx,而後上傳到centos系統的/etc/init.d/目錄,接着添加可執行權限,最後執行添加到開機啓動的命令:chkconfig --add nginxchkconfig nginx on便可。web

最後,咱們能夠使用以下命令對Nginx服務進行操做:shell

######啓動Nginx服務
[root@typecodes ~]# service nginx start
######中止Nginx服務
[root@typecodes ~]# service nginx stop
######重啓Nginx服務
[root@typecodes ~]# service nginx restart
######Nginx服務的狀態
[root@typecodes ~]# service nginx status
######在Nginx服務啓動的狀態下,從新加載nginx.conf這個配置文件
[root@typecodes ~]# service nginx reload
